Two Giant Killer Hornet Colonies Fight to the Death


[MUSIC PLAYING] NARRATOR: The Samurai scouts
bring news that there’s an army on its way. [BUZZING] They rally the troops. But it’s too late. The Bamboo Battalion is on them. The Rock Samurais are ambushed
at their own entrance. When times are tough,
giant killer hornets turn on their kind. It’s like on like,
giant on giant. Claws, stingers, and mandibles,
all weapons deployed and heads will roll. Disabling the enemy is
the primary strategy. Beheading and severing
limbs, the mandibles are the ultimate weapon of war. It’s impossible to
determine who’s winning until the pillaging starts. The marauding Bamboo
giants enter the fortress. They’re conquered
the Rock Samurais and they’ve struck gold. The precious nursery of
developing princesses is ransacked, next year’s
queens killed and cannibalized in their chambers. The sentry can do nothing
but witness the devastation of her precious family.

For These Tiny Spiders, It’s Sing or Get Served | Deep Look


Behold a very small and rather cute spider. This is clypeatus. A jumping spider. He doesn’t spin webs. Instead he uses silk as a lifeline, reeling
it out as he hops from place to place. But right now, he’s looking for a mate. The thread of a female spider that he can
trace back to its source. Problem is, she may have other priorities. While he’ll jump on pretty much anything
that moves…She only mates once. She’s picky. So he’s going to make his case… on the
dancefloor. Male jumping spiders perform courtship displays
that would make Bob Fosse proud. Jazz hands, leg-lifts…they even shimmy their
pedipalps. But he needs a soundtrack. So, by beating together the front and back
halves of his body, he creates vibrations that travel through the ground. This is what her ears look like. Tiny membranes stretched across slits in her
legs. To study these jumping spider pulses, researchers
at the University of California Berkeley use a sophisticated laser vibrometer developed
for quality-testing cars and airplanes. It turns those vibrations into something we
can hear. And guess what? It’s a song. The first verse sounds like this. A fast heartbeat. Thump thump thump thump thump thump thump. Then, more thumping. Followed by something new. A “BOOM.” This is verse two. That pattern, over and over again. For verse three he adds a third element. Almost like he’s casting a spell, right? From species to species, and there are thousands
of different jumping spiders, the songs vary. But one thing never changes: Male jumping
spiders sing like their lives depend on it. Because they do. She may mate with him. She might refuse. But she might just eat him instead. When the Berkeley scientists prevented the
males from singing while they danced, the females were three times as likely to hunt
them as prey. So he needs to go big. The closer he gets to her, the more danger
he’s in. The dance and the song get more and more urgent. But even with all that… She’s still calling the shots. Hi, it’s Amy. If female spiders are picky, with males, the
bar is so, so low. He’ll do this courting song and dance with
pretty much anything. In the lab, scientists use frozen specimens
this one. A dead female spider! And he still tries to mate with her. While you’re here, subscribe to Deep Look,

So … Sometimes Fireflies Eat Other Fireflies | Deep Look

So … Sometimes Fireflies Eat Other Fireflies | Deep Look


If you think there’s something romantic
about fireflies glowing on a warm summer night… You’d be right. But what you don’t see, is the dark side
of this luminous display. Firefly flashes are a secret code, a language
of light. The light comes from a masterful bit of chemistry. A bioluminescent reaction that generates light
but no heat. So what are they saying? Well, males on the wing are advertising themselves
to females with a bit of sexy skywriting. Take the common Eastern firefly. His signature move? A fishhook-shaped maneuver. Which is why his species is sometimes called
the “Big Dipper.” Her reply is more subtle: a single, slow pulse
from her heart-shaped lantern. Our “Big Dipper” comes bearing a “nuptial
gift,” a present of more than 200 assorted nutrients… kind of like a box of chocolates. Here’s the handoff. Some are lucibufagins — defensive chemicals
fireflies secrete to ward off predators like spiders and birds. These defensive chemicals may help protect
her. Firefly codes are so reliable that anyone
can speak the language. But we’re not the only codebreakers listening
in. Meet Photuris. She’s also a firefly — a larger, stronger
one than the Big Dippers. But she has a weakness. Her species can’t make its own lucibufagins. They have fewer defenses against predators. So she sets a trap to get some. She mimics the glow of other firefly females
— luring in the males of that species. When Mr. Big Dipper shows up with his chemical
gift, she moves in… sucks up those defensive chemicals that she
desperately needs… …then makes a meal of the rest of him. Most fireflies don’t even eat during the
few weeks they spend as adults. But he’s not totally defenseless. If she’s not quick enough, he can secrete
a gooey compound that sticks in her jaw and lets him escape. Another gift from the master chemist. Hey there, it’s Lauren. I know you see that ‘Subscribe’ button there. Here’s what it’ll get you. New Deep Look episodes every two weeks. Keep up with all the weird, gross, and wonderful
things we’re working on. Thanks, and see you soon.

Drug Crazed – Florida’s new drugs epidemic

Drug Crazed – Florida’s new drugs epidemic


What is your name? Haha. Ahhh. It’s the designer drug that’s wreaking havoc
across the United States, a potent chemical mix that is tearing families apart. I have lost my brother and my best friend.
I don’t know if I will ever get them back. Plunging users into psychosis… He feels like there’s mind control, he feels
like he has no control over his mind. And inducing unimaginable behaviour. He went ear to ear with a large butcher knife
and cut his throat. For
the last few years, bath salts have flown
under the radar. A synthetic chemical cocktail said to mimic the effects of cocaine and methamphetamine,
it is difficult to detect and gained an underground following as a cheap and legal high. Most
people had never heard of it until earlier this year when an unthinkable act shocked
the world. Drugs known as bath salts are blamed for a
gruesome scene in Miami. Two naked men found off the Macarthur Causeway
on Saturday afternoon, one literally chewing the face off the other. Rudy Eugene was killed by police, after he
inexplicably ate the face of a homeless man, Ronald Poppo. All that’s left were his goatee. His eyeballs
are gone, his face, it is unbelievable. Although bath salts were blamed, no clear
link was established but the case set off a media frenzy. I’m calling it a bath salt epidemic in the
country. They make people crazy. A couple of cannibalism and self-mutilation
cases could be linked to bath salts. They’ve got to get it off the market. They’re
killing people. New York State is in the midst of a bath salts
crisis. That store right over there, 420 Emporium,
is where my brother began buying bath salts. Desperate for intervention, Nicolette Lang
is protesting outside the shop she claims supplied bath salts to her son. He kept telling us his house was haunted.
We would go check the house and have priests go with us. We would believe in him. He believed
in himself, but came to find out it was bath salts. The drug has only recently been made illegal,
but many shops continue to sell it under the counter. Your sister has been using the bath salts? Yeah. I think over a month. She has. Does she buy them here? Yes. How much does she use, do you know, has she
ever said? She has a caterpillar every two hours. What’s that, a tube, a vial every two hours?
She was going through over a gram a day? Yes. Every individual that markets or sells or
distributes this in a convenience store should have to consume about five grams of it before
he’s able to sell it over the counter. I would like to see if they survive. Richard Sanders has a right to be bitter.
His son Dickie was a rising BMX star in a league of his own and with the world at his
feet. At 21, he still shared the closest of bonds with his father, a respected Louisiana
doctor. There was a goodbye on the telephone. It was
a goodbye four or five times. It was always, “Love you dad” and it was always, “Okay, son,
love you too”. It was always Dickie with, “I love you dad again” it was special. Dickie’s life began to unravel when he was
booked on a marijuana driving charge and subjected to a stringent drug testing regime. To skirt
the system, Dickie decided to try bath salts. Within hours of taking them, his paranoia
spiralled out of control. He was seeing police helicopters and then
again police cars out in front of the front yard. I told him at that point, I said, ‘Dickie,
we just walked outside, partner, there’s no one outside – I just showed you there’s no-one
out there. This is so crazy, why are you doing this?’ I said, ‘I will basically go outside
and see if there’s any police. If there are any police out here, I will have them come
inside and you ought to be arrested because you’re acting so crazy’. He immediately grabbed a knife, went ear to
ear with a large butcher knife and cut his throat. Holding the knife up and said, “Dad,
what am I doing – what’s going on — what’s happening dad, I don’t want to hurt myself,
what’s happening, what am I doing?” Dickie was rushed to hospital to have the
wound stitched but when he got home the next day the psychosis returned. His whole personality began to change. He
became extremely anxious. He became extremely concerned about locking the doors and relocking
the doors in all of the house. By now Dickie had not slept for days. Exhausted,
Richard fell asleep clutching his son, but early in the morning he woke with a start. I came down the steps here and attended him
and rolled him over and he just slumped. Beside him lay the rifle he’d used to shoot
himself in the mouth. When you realise there’s nothing else to get
done, basically, you cry. You scream. The incredulous nature of this chemical – the
mystique of it. The feeling as a physician, that I wasn’t able to predict or see any evidence
of suicidal ideation in my son. Driven by his grief and his anger, Richard
Sanders probed the pharmacology of bath salts for clues to explain his son’s psychosis and
soon found a culprit – the chemical known as MDPV. It inhibits re-uptake of Norepinephrine and
Dopamine and keeps those neuro-transmitters firing off on the nerves that are causing
the psychoactive process, whether it’s paranoid delusional activity, extreme thought and content
disorder processes and things like that. This is a public health issue because we have
no idea what this does to people. For Special Agent Jim Burns bath salts are
the most problematic drug he’s ever encountered. While bath salts are banned, traffickers continue
to modify the chemical composition, to stay a step ahead of the law. New York State passed a bath salts law a year
or so ago, and they specified five different chemicals. No sooner had they past that then
some enterprising chemist somewhere, well, they tweaked the chemical formula, and now
it’s no longer the substance that was banned in the state law. So you’re back to square
one. Nevertheless, New York State Troopers are
fighting back and I’ve been invited to witness their first strike. We’re just going in as we speak. You can see
them pulling right out. Staff in the smoke shop offer no resistance
as the authorities swoop, one of hundreds of raids taking place simultaneously across
the country. In the city of Utica, bath salts are proving to be a major headache. The crime
rate is soaring. The majority of our crimes stem from the drug
trade, the drug use, you know, someone committing a burglary in order to support their habit. Get out of the way! If we get a call involving someone who we
think may be intoxicated on bath salts, there’s definitely not just a one officer call. We
know the potential for violence. In this city, emergency laws have been passed
allowing police to arrest users of the drug. This is what she had on her. She said she
was going to Ted’s Smoke Shop, went by earlier, to get some bath salts. But this is all she
had. But arresting users will have minimal impact
and at the DEA, Jim Burns is focussing on the supply chain. This is part of a seizure that the Buffalo
office made earlier this year. This store had an AK-47 with a high capacity magazine
that they kept loaded and behind the counter. What is especially disturbing to law enforcement
officials is the origin of the ingredients in bath salts, traced back to chemical manufactures
in China. We have an office in Beijing, and we’ve given
a lot of the intelligence and information we’ve developed in a number of our cases here
in upstate New York that point, that the sources being in China. They allowed it to, not just come to America,
but it’s prevalent. So when they finally did decide to do something, it’s kind of like,
it’s too late for the thousands who have been affected and it’s kind of “screw you”. Tiffany Russell has little patience for government
pondering over a drug that she says has destroyed her family. I went from being a mum who had a wonderful
handsome intelligent productive son, who had everything going for him, that was the light
of his life, to… I don’t have a child. It’s not even if he were dead, it’s almost as if
he never existed. Tiffany’s son, Skyler, gained national attention
at 14, as one of the young stars of the TV series, ‘Endurance’. Now 24, Skyler has been
addicted to bath salts for almost three years. This is just a few items that I collected.
So the bath salts come in a package like this. He will leave them lying around, not remembering
where he put them, and I will confiscate them. In an effort to shock Skyler out of his addiction,
Tiffany recorded their discussions on video. How does it make you feel? Energised. That’s it. You don’t look so energised. It’s because I didn’t sleep all night. It makes me sad now watching it. My heart
aches. Do you see bath salts having robbed you of
your son? Absolutely. It’s robbed him of a life. It’s
taken his life, it’s taken his soul. I still have my life and my health and he doesn’t
and he doesn’t even know it. With nowhere else to turn for support, she
sought help from the US reality show, ‘Intervention’, which offers addicts a chance to undergo rehab. I built a weapon… to fight the phase people.
If I hit the head with the top part, they die basically. This could kill them, if I
put it through their heart or brain. The intervention failed and Skyler was later
diagnosed with schizophrenia and Tiffany believes the drug is firmly to blame. I don’t think Skyler had any disposition for
schizophrenia or other psychosis. This happened a month after using the bath salts and I believe
it’s all induced by the bath salts. Skyler has agreed to meet me. Lucid and sober,
he lets me film as he drives around Phoenix looking to buy bath salts. You got bath salts man? I don’t, bro. Do you know who does? I don’t, because if you get caught it’s 10
years, felony charges. Damn. With the ban in place, bath salts are proving
harder to find. But Skyler is determined to find it. I want the drug. I want things that other
people consider to be bad. As far as I’m concerned, fuck ’em. With Skyler refusing to co-operate, Tiffany
has been left with few options and remains angered at the government’s failure to prevent
the bath salts scourge. They allowed the bath salts to be legal, they
allowed the access, they knew what the bath salts could do. There’s record of it in Europe.
It existed years before it existed here. In fact the forerunner to bath salts was a
synthetic compound popular in Britain known as Meow Meow. It was banned there in 2010
in a blaze of worldwide publicity. But, astonishingly, it failed to show up on the DEA’s radar. Was there any reason it didn’t come on a bit
earlier, that the US wasn’t prepared for a wave of bath salts to emergency here? You know, Nick, I can’t really answer that.
With this, you know, it just sort of like snuck up on everybody. Allowing bath salts to flourish has made the
problem intractable and many see it as one of America’s biggest drug intelligence failures.
Others go further – convinced it was America’s continuing crackdown on soft drugs that is
ultimately to blame leading to the creation of this deadly new high. The rug was pulled out from underneath him
and the system won. The system won. The system that created and entangled his life won.
